In the hot summer, the temperature in many places remains high. Many people choose ice cream, ice cream, popsicles and other frozen drinks to cool down. Faced with the dazzling array of goods in the freezer, have you encountered difficulties in choosing? Let’s learn about these frozen drinks!
What is a frozen drink?
According to GB 2759-2015 national standard for food safety frozen drinks and ingredients, frozen drinks are solid or semi-solid food made from drinking water, sugar, milk, dairy products, fruit and vegetable products, beans, edible oils and other kinds of raw materials, with or without other excipients, food additives, nutritional enhancers, through ingredients, pasteurization or sterilization, freezing or freezing and other processes.
What are the categories of frozen drinks?
According to the definition in gb/t 30590-2014 classification of frozen drinks, frozen drinks can be divided into ice cream, ice cream, snow mud, popsicle, sweet ice, edible ice, etc. Ice cream or ice cream is usually the most expensive frozen drink in the freezer. The process of ice cream and ice cream is similar, and the raw materials are mainly drinking water, milk or dairy products, grease, etc. the difference is that ice cream is a volume expanding frozen drink. Although it is sometimes not easy to distinguish from the packaging, the physical and chemical indicators of ice cream and ice cream are actually quite different.
In gb/t 31114-2014 frozen drink ice cream, for different types of ice cream, the protein content is required to be not less than 2.5g/100g or not less than 2.2g/100g, and the fat content is required to be not less than 5.0g/100g to not less than 8.0g/100g. The requirements for different types of ice cream in gb/t 31119-2014 frozen beverage ice cream are that the protein content is not less than 0.8g/100g or 0.4g/100g, and the fat content is not less than 2.0g/100g or 1.0g/100g. In other words, the protein content of ice cream may be 3-6 times that of ice cream, and the fat content will also be 2-8 times that of ice cream. Due to the high milk fat content, the taste of ice cream is usually smoother. Compared with ice cream, ice cream has higher water content, so it will have higher hardness. Snow mud, popsicles and sweet ice are frozen drinks made from drinking water and sugar.
Are frozen drinks safe?
In the food safety sampling inspection of frozen drinks by market supervision and administration departments at all levels in the first half of 2022, most of the unqualified items are microbial indicators exceeding the standard, such as the total number of colonies exceeding the standard, coliforms exceeding the standard, Listeria monocytogenes exceeding the standard, and some ice cream proteins failing to meet the standard. The overall qualification rate of frozen drinks is more than 98%.
GB 2760-2014 national food safety standard for the use of food additives stipulates that specific thickeners, stabilizers, emulsifiers, sweeteners, colorants and other food additives are allowed to be used in ice cream and ice cream. As long as they are used within the scope of the national food safety standard, they are safe.
How to choose frozen drinks?
Most frozen drinks are high in sugar and fat. Once they reach the appropriate temperature range, microorganisms will multiply in large numbers. If the sanitary conditions are not controlled in place during production and processing, or the operation of product transportation and storage is not standardized, microbial indicators may exceed the standard. Therefore, when buying frozen drinks, consumers should try to choose regular supermarkets and shopping malls, choose products with clear labels and complete seals, and choose products with normal shape and color and fresh date. Temperature fluctuations should also be avoided during storage to prevent microbial proliferation. Frozen drinks with changes in the shape or flavor of the contents are not recommended.
In hot summer, frozen drinks are undoubtedly a good helper for relieving summer heat and cooling. However, the temperature of frozen drinks is low. It is recommended to eat them between meals to avoid irritation to the gastrointestinal tract. We should also avoid eating frozen drinks immediately after exercise. Blood circulation accelerates after exercise. Low temperature frozen drinks will cause vasoconstriction and may induce cardiovascular and cerebrovascular diseases. Frozen drinks often contain a lot of sugar and fat. For the elderly, children, patients with hypertension, diabetes and people with low immunity, we should pay attention to moderate consumption of frozen drinks. Author and work information
